Title: CAP ASSEMBLY FOR A MEDICAMENT DELIVERY DEVICE
Abstract:
The present disclosure relates to a cap assembly (5) for a medicament delivery device, comprising: a cap (7) having a tubular body (7b) defining an axially extending distal opening (7c) and configured to be mounted to a proximal end of a medicament delivery device, wherein the cap (7) has a bottom structure (7e) defining a proximal end of the distal opening (7c), wherein the bottom structure (7e) has a cam structure (7f) provided inside the tubular body (7b), and wherein the tubular body (7b) has inner walls provided with radial recesses (7d), and an elongated squeeze member (9) configured to be received in the distal opening (7c) of the tubular body (7b), and having a longitudinally extending channel (9d) configured to receive a delivery member shield, and which squeeze member (9) has radial arms (9e) flexible in the radial direction and forming part of a wall of the channel (9d), wherein the squeeze member (9) has a proximal end face (9a) configured to displacement of the squeeze member (9) from a first position in which the proximal end face (9a) bears against the cam structure (7f) to a second position in which the squeeze member (9) is received further by the cap (7) causes rotation of the squeeze member (9) relative to the cap (7), wherein the radial arms (9e) are configured to engage with a respective radial recess (7d) of the tubular body (7b) in the first position of the squeeze member (9), and wherein the radial arms (9e) are configured to disengage from the respective radial recess when the squeeze member (9) is displaced from the first position to the second position and rotated, whereby the flexible radial arms (9e) are pressed into the channel (9d) by the inner walls of the tubular body (7b), reducing a cross-sectional area of the channel (9d).
